ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
El paulatino aumento de la profundidad a la que se han ido fondeando las plataformas petrollferas, de perforation y/o exploration, en busca de nuevos yacimientos de 20 hidrocarburos, hizo cambiar el tipo de union, de estructuras Jacket, rlgidamente unidas al fondo, a plataformas semisumergibles fondeadas, mediante cadenas, o bien para mayores profundidades se recurre al fondeo mediante cadena y cable, y mas recientemente se opta por el fondeo mediante cables tensionados, tambien conocido como TLP.The gradual increase in the depth at which the oil, drilling and / or exploration platforms have been anchored, in search of new 20 hydrocarbon deposits, changed the type of union, Jacket structures, rigidly attached to the bottom, to semi-submersible platforms anchored, by chains, or for greater depths, anchoring is used by chain and cable, and more recently, funding is chosen by means of tensioned cables, also known as TLP.
25 Dado que no se puede construir in situ la plataforma, esta viene transportada desde grandes buques de elevation o desde gabarras especlficas que posiciona primero la parte inferior de la plataforma, que esta en contacto con el agua, y posteriormente la parte superior de la plataforma o topside, que es la que posee la funcionalidad especlfica de la plataforma.25 Since the platform cannot be built on site, it is transported from large ships of elevation or from specific barges that first positions the bottom of the platform, which is in contact with water, and then the top of the platform or topside, which is the one that has the specific functionality of the platform.
30 En caso de que se necesite espacio para diferentes funciones y/o que estas no puedan ser incluidas dentro de una sola plataforma, no queda, por lo tanto mas alternativa, que construir otra plataforma, que debera tener su fondeo propio, en cualquiera de las alternativas existentes.30 In the event that space is required for different functions and / or that these cannot be included within a single platform, there is, therefore, no alternative but to build another platform, which should have its own funding, in any of The existing alternatives.
El fondeo de plataformas es una de las partidas que representan un mayor porcentaje del precio total de la plataforma, por lo que el problema que se plantea es la busqueda de una solucion de fondeo para un conjunto de plataformas que minimice los costes asociados.The funding of platforms is one of the items that represent a greater percentage of the total price of the platform, so the problem that arises is the search for a funding solution for a set of platforms that minimizes the associated costs.
5 DESCRIPCION DE LA INVENCION5 DESCRIPTION OF THE INVENTION
La plataforma oceanica que constituye el objeto de esta invention ha sido disenada para resolver los problemas antes expuestos, ya que permite unir varias plataformas compartiendo un mismo fondeo, abaratandose as! drasticamente el precio de la plataforma.The oceanic platform that constitutes the object of this invention has been designed to solve the problems described above, since it allows to join several platforms sharing the same funding, thus lowering it! drastically the price of the platform.
1010
La presente invencion propone que la plataforma oceanica disponga de una unidad central en la que se situa el fondeo y de al menos una, normalmente varias, plataformas satelites acoplables a la unidad central mediante una union o articulation tipo rotula.The present invention proposes that the oceanic platform has a central unit in which the anchorage is located and at least one, usually several, satellite platforms that can be attached to the central unit by means of a joint or joint type.
15 La articulacion tipo rotula comprende una rotula y un apoyo de rotula en la que puede girar la rotula. Se ha previsto que modo preferente que las plataformas satelites dispongan de las rotulas y que la unidad central incorpore el apoyo de rotula en las que acoplan las rotulas de las plataformas satelites, aunque sin descartar la posibilidad de que la unidad central disponga de las rotulas y las plataformas satelite incorporen los apoyos de rotula.15 The ball joint includes a ball and a ball bearing support in which the ball can rotate. It is envisaged that preferential mode that the satellite platforms have the markers and that the central unit incorporates the patella support in which the pallets of the satellite platforms are coupled, although without ruling out the possibility that the central unit has the markers and The satellite platforms incorporate the headlamp supports.
20twenty
Los centros de giro de las rotulas se pueden encontrar ubicados en la llnea de flotation, por encima o por debajo indistintamente, donde esto se elegira en funcion de la geometrla de las plataformas satelites, preferentemente por encima de la llnea de flotacion.The centers of rotation of the markers can be found located on the flotation line, above or below indistinctly, where this will be chosen depending on the geometry of the satellite platforms, preferably above the floating line.
25 Para limitar los movimientos, se dispone a su vez de una serie de llneas de union, entre la unidad central y las plataformas satelite que amortiguan los movimientos relativos entre estas, donde las llneas de union son preferentemente cables o cadenas que limitan los movimientos en los 6 grados de libertad de la rotula. Los movimientos relativos de la plataforma satelite y de la unidad central se limitan y/o amortiguan por lo tanto, en funcion de 30 la rigidez y de la tension de las llneas, donde a mayor tension y/o rigidez, menores movimientos relativos.25 In order to limit the movements, a series of connecting lines is also available, between the central unit and the satellite platforms that dampen the relative movements between them, where the joining lines are preferably cables or chains that limit the movements in the 6 degrees of freedom of the label. The relative movements of the satellite platform and the central unit are therefore limited and / or dampened, depending on the stiffness and tension of the lines, where the greater the tension and / or rigidity, the lower the relative movements.
Por lo tanto la unidad central y las plataformas satelites pasan a formar un unico cuerpo articulado, y por tanto pasan a compartir el fondeo asociado a la unidad central.Therefore, the central unit and satellite platforms become a single articulated body, and therefore they share the funding associated with the central unit.
La distribution de las plataformas satelite es radial con respecto a la unidad central, y por tanto la distribution de las articulaciones tipo rotula es asimismo radial. El numero maximo de plataformas satelite que se pueden adosar a la unidad central vendra definido por el numero de articulaciones previstas en la unidad central.The distribution of the satellite platforms is radial with respect to the central unit, and therefore the distribution of the ball joint is also radial. The maximum number of satellite platforms that can be attached to the central unit will be defined by the number of joints provided in the central unit.
55
Al unirse las plataformas satelite a la unidad central aumenta la estabilidad del conjunto formado por la unidad central y las plataformas satelites, dado que pasan a formar un conjunto articulado con mayores desplazamientos e inercias que por separado, donde el comportamiento dependera de la rigidez de los cables empleados en la union entre unidad 10 central y plataformas satelites, que se encargan de contrarrestar la amplitud y frecuencia, de los giros, balance, guinada y cabeceo, que se producen en cada articulation de rotula.By joining the satellite platforms to the central unit increases the stability of the set formed by the central unit and the satellite platforms, since they become an articulated set with greater displacements and inertia than separately, where the behavior depends on the rigidity of the cables used in the union between central unit 10 and satellite platforms, which are responsible for counteracting the amplitude and frequency, of the turns, balance, guinate and pitching, which occur in each joint of articulation.
De modo preferente se plantea que la unidad central de la plataforma sea semisumergible.Preferably, it is proposed that the central unit of the platform be semi-submersible.
15 La presente invention plantea por tanto la alternativa de emplear un fondeo comun para un grupo de plataformas, en el que una de ellas, la unidad central, esta siempre fondeada, por ejemplo con anclas y cadenas, o con cables tensionados, o unida rlgidamente anclada al fondo mediante una estructura, y el resto, las plataformas satelite, se pueden anadir a voluntad a la unidad central fondeada.The present invention therefore proposes the alternative of using a common anchorage for a group of platforms, in which one of them, the central unit, is always anchored, for example with anchors and chains, or with tensioned cables, or rigidly connected anchored to the bottom by a structure, and the rest, the satellite platforms, can be added at will to the anchored central unit.
20twenty
La estabilidad y con ello la operatividad de la plataforma se consigue independientemente del numero de plataformas satelite que se unen a la unidad central, pues cada una de ellas establece su vinculacion a la unidad central de forma independiente.The stability and with it the operability of the platform is achieved independently of the number of satellite platforms that join the central unit, since each of them establishes its link to the central unit independently.
25 Es de destacar por tanto que este modo de union permite anadir o quitar plataformas satelites a/de la unidad central de forma sencilla, y por tanto facilita la adaptation de la plataforma oceanica a la necesidad del momento de disponer de un espacio adicional para actividades complementarias mediante la incorporation temporal de las plataformas satelites.25 It is noteworthy therefore that this mode of union allows to add or remove satellite platforms to / from the central unit in a simple way, and therefore facilitates the adaptation of the oceanic platform to the need of the moment to have an additional space for activities Complementary through the temporary incorporation of satellite platforms.

REALIZACION PREFERENTE DE LA INVENCIONPREFERRED EMBODIMENT OF THE INVENTION
A continuation se describe un modo de realization preferente de la plataforma oceanica polivalente que constituye el objeto de esta invention.A preferred embodiment of the multi-purpose ocean platform that is the subject of this invention is described below.
55
En la figura 1 se muestra una plataforma oceanica formada por un unidad central (1) y dos plataformas satelites (2, 2’) que comparten un fondeo comun situado en la unidad central (1), la cual dispone de unos apoyos de rotulas (9, 9’), en las cuales se encuentran acopladas unas rotulas (3, 3’) de las plataformas satelites (2, 2’).Figure 1 shows an oceanic platform formed by a central unit (1) and two satellite platforms (2, 2 ') that share a common anchorage located in the central unit (1), which has ball bearing supports ( 9, 9 '), in which are coupled to pads (3, 3') of the satellite platforms (2, 2 ').
1010
Las rotulas (3, 3’) se distribuyen radialmente con respecto a la unidad central (1), donde en este modo de realizacion, en la figura 1 por ejemplo, se observa que disponen de 2 rotulas (3, 3’) separadas entre si 180 grados segun el plano de la flotation.The labels (3, 3 ') are distributed radially with respect to the central unit (1), where in this embodiment, in Figure 1 for example, it is observed that they have 2 labels (3, 3') separated between if 180 degrees according to the plane of the flotation.
15 Para limitar la amplitud de los movimientos la plataforma comprende una serie de cables (4), representados en las figuras 5 a 8, que unen la unidad central (1) con las plataformas satelites (2, 2’). Dado que la rotula (3, 3’) permite las rotaciones en los tres ejes, no posee reacciones tipo momento en la estructura que la soporta. La rigidez de los cables (4), que es debida al tipo de material, a la section y longitud de la misma, determina la respuesta y por 20 tanto interaction entre la unidad central (1) y las plataformas satelites (2, 2’).15 To limit the amplitude of the movements, the platform comprises a series of cables (4), represented in figures 5 to 8, that link the central unit (1) with the satellite platforms (2, 2 ’). Since the label (3, 3 ’) allows rotations in all three axes, it does not have moment type reactions in the structure that supports it. The stiffness of the cables (4), which is due to the type of material, the section and length of the same, determines the response and therefore both interaction between the central unit (1) and the satellite platforms (2, 2 ' ).
La rotula (3, 3’) se situa cercana a la flotation, tal y como se aprecia en la figura 4, de manera que se pueda corregir, sin generar otros movimientos, los movimientos de cabeceo, balance y guinada, que son corregidos por la presencia de los cables (4) y donde los 25 desplazamientos sin giro en los tres ejes, son transmitidos de la plataforma satelite (2, 2’) a la unidad central (1).The label (3, 3 ') is located close to the flotation, as can be seen in Figure 4, so that it is possible to correct, without generating other movements, the pitching, balancing and guiding movements, which are corrected by the presence of the cables (4) and where the 25 displacements without rotation in the three axes are transmitted from the satellite platform (2, 2 ') to the central unit (1).
Esto da como resultado una plataforma mas estable, tanto en el caso de la unidad central (1), como de las plataformas satelites (2, 2’), ya que pasan a formar un cuerpo flotante 30 solidario y articulado.This results in a more stable platform, both in the case of the central unit (1), as well as the satellite platforms (2, 2 ’), since they form a floating and supportive floating body 30.
En este modo de realizacion la unidad central (1) posee dos apoyos de rotula (9, 9’) y por lo tanto se le pueden adosar hasta dos plataformas satelite (2, 2’) dotadas cada una de una rotula (3, 3’).In this embodiment, the central unit (1) has two ball bearing supports (9, 9 ') and therefore it is possible to attach up to two satellite platforms (2, 2') each equipped with a label (3, 3 ').
Las plataformas satelite (2, 2’) pueden tener cualquier forma, si bien en este modo de realizacion, forman dos estructuras flotantes donde la rotula (3, 3’) se encuentra en la mitad de la plataforma satelite (2, 2’), tal y como se observa en la figura 4 por ejemplo, la cual se prolonga transversal mente a la direccion de la union, en ambos sentidos, formando un 5 cuerpo con unas relaciones de eslora manga como las que se encuentran en buques de transporte de mercanclas a granel. El espacio que posee esta plataforma satelite (2, 2’), puede estar concebido para almacenar mercanclas, como contenedores o mercanclas a granel o destinarse a espacios de ocio como hoteles o restaurantes.The satellite platforms (2, 2 ') can have any shape, although in this embodiment, they form two floating structures where the label (3, 3') is in the middle of the satellite platform (2, 2 ') , as can be seen in Figure 4 for example, which extends transversely to the direction of the union, in both directions, forming a body with sleeve length ratios such as those found in transport ships of bulk goods. The space that has this satellite platform (2, 2 ’), can be designed to store goods, such as containers or bulk merchandise or go to leisure spaces such as hotels or restaurants.
10 En este modo de realizacion las plataformas satelites (2, 2’) estan concebidas para orientarse a la corriente dominante del emplazamiento donde se situe la plataforma y de este modo reducir las reacciones en el fondeo, de ahl que se ofrezca el menor area posible a la corriente, al situarse las plataformas satelites (2, 2’) como dos patines junto a la unidad central (1).10 In this embodiment, the satellite platforms (2, 2 ') are designed to be oriented to the dominant current of the location where the platform is located and thus reduce the reactions in the funding, hence offering the least possible area to the current, when placing the satellite platforms (2, 2 ') as two skates next to the central unit (1).
15fifteen
En este caso, tal y como se representa en la figura 1, las plataformas satelites (2, 2’) poseen puntos de amarre exteriores (11) e interiores (10), de manera que se puedan realizar operaciones simultaneas con varios buques (12,13), representados en las figura 2, de diferente tamano al mismo tiempo, pudiendo ser el caso de buques portacontenedores (13) 20 o buques OSV (12).In this case, as shown in Figure 1, the satellite platforms (2, 2 ') have exterior (11) and interior (10) mooring points, so that simultaneous operations can be carried out with several ships (12 , 13), represented in figures 2, of different sizes at the same time, which may be the case of container ships (13) 20 or OSV ships (12).
La unidad central (1) posee un fondeo convencional tipo spread mediante cadena en este modo de realizacion, si bien este dependera de la profundidad de la lamina de agua en que opere la plataforma, pudiendo ser igualmente cadena y cable o mediante cables tensionados 25 TLP.The central unit (1) has a conventional spreading type by chain in this embodiment, although this will depend on the depth of the water sheet in which the platform operates, it can also be chain and cable or by tensioned cables 25 TLP .
Tal y como se aprecia en la figura 3, la plataforma es del tipo semisumergible, y consta de un flotador (7) inferior al que se le unen una serie de patas (8) que soportan la parte superior de la unidad central (1) o topside. La unidad central (1) posee una configuracion hexagonal 30 en la cual las patas (8) se situan en los vertices de la misma, y donde la seccion de las patas (8) es cuadrangular. Tanto en el flotador (7), asimismo de configuracion hexagonal, como en las patas (8), los bordes se suavizan, uniendose las aristas mediante planchas de radio constante, evitandose de esta manera los torbellinos en esta zona.As shown in Figure 3, the platform is semi-submersible, and consists of a lower float (7) to which a series of legs (8) that support the upper part of the central unit (1) are attached. or topside. The central unit (1) has a hexagonal configuration 30 in which the legs (8) are located in the vertices thereof, and where the section of the legs (8) is quadrangular. Both in the float (7), also of hexagonal configuration, as in the legs (8), the edges are softened, joining the edges by means of plates of constant radius, thus avoiding the whirlpools in this area.
En esa misma figura 3 se observa que la unidad central (1) incorpora asimismo unos molinetes de las cadenas (5), que se situan justo por debajo del denominado topside, en unas estructuras construidas a tal efecto situadas en cada una de las patas (8), asl como disponen en dichas patas (8) de una gula y freno para cadena (6), cercanas al punto mas 5 bajo de la plataforma.In the same figure 3 it can be seen that the central unit (1) also incorporates chain windings (5), which are located just below the so-called topside, in structures constructed for this purpose located on each of the legs ( 8), as well as on said legs (8) of a glutton and chain brake (6), close to the lowest point 5 of the platform.
En este modo de realization, las uniones mediante cables (4) de la unidad central y de la plataforma satelite se realizan a ambos lados de la rotula (3, 3’), ver figuras 5 a 8, y donde unen la parte inferior de la unidad central (1) con la parte inferior de la plataforma satelite (2, 10 2’) y del mismo modo la parte superior de la unidad central (1), con la parte superior de laIn this mode of realization, the cable connections (4) of the central unit and the satellite platform are made on both sides of the label (3, 3 '), see figures 5 to 8, and where they join the lower part of the central unit (1) with the lower part of the satellite platform (2, 10 2 ') and similarly the upper part of the central unit (1), with the upper part of the
plataforma satelite (2, 2’). Estas uniones son simetricas con respecto de la rotula (3, 3’), de manera que con ese esquema de union de cables tambien se amortiguan los movimientos relativos de guinada entre la unidad central (1) y la plataforma satelite (2, 2’).satellite platform (2, 2 ’). These joints are symmetrical with respect to the label (3, 3 '), so that with this cable connection scheme the relative guiding movements between the central unit (1) and the satellite platform (2, 2' are also damped ).
